Wind energy is from the kinetic energy of moving air. We harness wind energy with large wind turbines located on land or in the ocean. Wind turbines are technology we got from improving the structure of good old windmills used to harvest wind power in the 18th/19th century. 

As the wind blows against the wind turbines, they generate electricity we can use for various activities. However, the wind power gained from harnessing wind energy varies by location. The best place to get enough wind power is by setting up turbines in sea or freshwater locations, i.e., offshore.
